Abstract
A flanged joint connection for connecting together by a bolted connection a pair of casing shells having connecting flanges. The connection reduces bearing stress concentrations adjacent fillets provided at the junction of the flange and the casing shell surface. A rectilinear edge portion is provided on a bolt head or a spacer, or both, to avoid point contact of the bolt head or spacer and the flange face or fillet. The rectilinear edge portion includes a convexly-curved surface that faces the fillet. The incidence of cracks between a bolt hole and the fillet, as well as the incidence of circumferential cracks between adjacent bolt holes is significantly reduced.
